Audacity Version 1.2.6 Free

Software program for recording and editing audio files such as songs or podcasts

Audacity is a free cross-platform digital audio editor and recorder. It's fully compatible with Windows, Mac OS X, Linux and BSD. Besides recording and editing audio files, you can use it to post process all audio formats, including podcasts, by applying effects such as normalization, trimming, and fading in and out. As audio recorders and editors come, Audacity is quite a good one.
Using it, you'll be able to import and export WAV, AIFF, MP3, Ogg, Vorbis, and all file formats supported by libsndfile library. You'll also be able to apply sophisticated noise removal techniques by sampling the noise to be removed. Surface noises from records, for an instance, can be removed without hampering with audio's quality. Changing audio's pitch can also be accomplished without changing its speed.
There's quite an assortment of audio recorders and editors out there, but this one offers an extensive, comprehensive, and other words finishing with -sive, that make it a preferable choice.
